A malaria vaccine has become the first to provide 100% protection against the disease, confounding critics and far surpassing any other experimental malaria vaccine tested. It will now be tested further in clinical trials in Africa.

A messy winter storm is moving across the eastern half of the United States, threatening to delay drivers and fliers right before Thanksgiving Day, one of the busiest travel times of the year.

Weather forecasters say a few key atmospheric components joined forces to create this meteorological misery.

The storm is actually the same upper level low-pressure system, or trough (essentially a dip in the jet stream), that tore over the Southwest over the last few days, Brian Hurley, a meteorologist with the National Weather Service said. The storm dumped nearly a foot of snow in parts of northern New Mexico, prompted hundreds of flight cancellations in Texas and caused several deadly traffic accidents across the region, the Los Angeles Times reported.

India's GSLV Mk III rocket lifts off on its maiden voyage December 18, 2014 at 11:00 PM EST (9:30AM Indian Standard Time).

The flight was a complete success, testing the new rocket's flight profile, avionics systems and booster technology.

Two S200 solid fuel motors propelled the vehicle off the launch pad, followed by the liquid fuelled L110 core stage. The rocket will eventually boast a cryogenic third stage which will place payloads in their desired orbits.

cientists around the world are tracking a doomed cloud of gas as it makes a daring approach toward the monster black hole at the center of our Milky Way galaxy, a cosmic encounter that might reveal new secrets on how such supermassive black holes evolve.

The G2 space cloud, and its ultimate death by black hole, have been under close scrutiny since the cloud's fate was first identified in 2011. Now, the cloud is destined to be shredded by a supermassive black hole.

The butterfly, known as Lexias pardalis, had half its body covered in markings typical of the male of its species and half covered in female markings. "I thought: 'Somebody's fooling with me. It's just too perfect,'" said Chris Johnson, the volunteer who made the discovery while working on the Academy's Butterflies! exhibit. "Then I got goose bumps."

"It slowly opened up, and the wings were so dramatically different, it was immediately apparent what it was," he added, according to a statement about the discovery released Tuesday by Drexel.
